Its brushless motor enhances its durability and eliminates the need for maintenance associated with traditional motors. Users will appreciate the powerful performance, with a maximum rotational speed of 3450 RPM, making it effective for various grinding applications.

This model is well-suited for both DIY enthusiasts and professionals looking for a robust and safe cordless tool. Its safety features, lightweight design, and powerful brushless motor are significant advantages, while the lack of a battery in the package is a consideration for potential buyers.

Buying Guide for the Best Cordless Angle Grinders

Choosing the right cordless angle grinder can make a significant difference in your work efficiency and the quality of your projects. Cordless angle grinders are versatile tools used for grinding, cutting, and polishing various materials. When selecting the best one for your needs, it's essential to consider several key specifications to ensure you get a tool that matches your requirements and preferences.
Battery VoltageBattery voltage determines the power output of the cordless angle grinder. Higher voltage typically means more power, which is crucial for heavy-duty tasks. Common voltage ratings are 18V, 20V, and 36V. For light to medium tasks, an 18V grinder should suffice. For more demanding jobs, consider a 20V or higher model. Your choice should depend on the intensity and frequency of your work.
Battery Capacity (Ah)Battery capacity, measured in ampere-hours (Ah), indicates how long the battery will last on a single charge. Higher Ah means longer runtime. Typical capacities range from 2.0Ah to 5.0Ah or more. If you need the grinder for extended periods without frequent recharging, opt for a higher capacity battery. For occasional or short-term use, a lower capacity battery may be sufficient.
Disc SizeThe disc size determines the cutting depth and surface area the grinder can handle. Common sizes are 4.5 inches, 5 inches, and 7 inches. Smaller discs (4.5-5 inches) are suitable for precision work and lighter tasks, while larger discs (7 inches) are better for heavy-duty cutting and grinding. Choose a disc size based on the type of projects you plan to undertake.
No-Load Speed (RPM)No-load speed, measured in revolutions per minute (RPM), indicates how fast the disc spins when not under load. Higher RPMs mean faster cutting and grinding. Typical speeds range from 7,000 to 12,000 RPM. For general-purpose use, a grinder with around 10,000 RPM is usually adequate. For specialized tasks requiring high-speed operation, look for models with higher RPMs.
WeightThe weight of the cordless angle grinder affects its portability and ease of use. Lighter models (around 4-5 pounds) are easier to handle and reduce user fatigue, making them ideal for prolonged use or overhead work. Heavier models (6 pounds and above) may offer more stability and power but can be tiring to use for extended periods. Consider your physical strength and the nature of your tasks when choosing the weight.
Safety FeaturesSafety features such as adjustable guards, anti-kickback protection, and paddle switches are crucial for preventing accidents and ensuring safe operation. Adjustable guards protect you from debris, while anti-kickback features prevent the tool from jerking out of control. Paddle switches offer better control and can be quickly turned off in emergencies. Prioritize models with comprehensive safety features, especially if you are new to using angle grinders.
ErgonomicsErgonomics refers to the design and comfort of the tool. Look for features like soft-grip handles, adjustable side handles, and balanced weight distribution. These features make the grinder more comfortable to use and reduce strain on your hands and arms. If you plan to use the grinder frequently or for long periods, ergonomic design should be a top consideration to enhance comfort and productivity.
Brushless MotorA brushless motor is more efficient, generates less heat, and has a longer lifespan compared to brushed motors. Brushless motors also provide more power and better performance. If you need a reliable and durable tool for heavy-duty or professional use, opting for a grinder with a brushless motor is a wise choice. For occasional or light use, a brushed motor may be sufficient.
